The invention concerns an OADT module receiving a multi-carrier WDM signal and a first carrier is select (e.g. using a combination of bocking and selective tunable filters) and managed using O/E/O conversion functionalities. <??>That first carrier signal can be: extracted, inserted or converted (from 11 to 12) and, finally, combined with the other carriers, belonging to received WDM signal. <??>The other carriers, belonging to the WDM signal, can be sent to the input of a second OADT module and managed in the same way as the first one has been managed, implementing a scalable OADM architecture. <IMAGE>
